While for convenience of description the-head has been referred-to as.- a disk with parts cut away, it is essentially a-l memberhaving a body portion which normally hangs clearof the magazine and peripheral distal portions projecting fromthe sides thereof. 'l he'frame 33 is so'mounted that in its to or slightly greater than its distance from I the cut-away face 39 of the feeder head. It

will,"therefore,' be easily understood that, if

" theshaft 35 is rotated, when the cut-away 7 portion 39 is jparallel'with the line of feed,

as shown in Fig. 4, the magazine will be unobstructed and the strips 0, therein can Ifeed'downwardunder gravity. When the head has made a partial rotation, the i toothed'distal portions will tend to project" intofithemagazine, as shown by the'dotted' i lines-of Fig. 1, and move through the same withfamotion which'exerts a force partly "fflin, the direction of the line of feed and "fpartlyftoward the abutment wall 15. (See'- f1; Fig. 1). .When'a piece of Wood is in the magazine,

However, the frame 33'will swing downward in the head evidently cannot' assume the Fig. 1 or-in a clockwise direction viewing the head are projected in rapid'recurrence ,intofthe magazine to strlke a successlon of" Fig.fl3,.-and permit thehead to deliver 'a percussive blow on theside of the strip in the magazine -ten'ding to force it forward out from the discharge opening beneath the front wall 17 and at the same time pressing As the it against guidewalls 15 and21. shaft 35 is rotated, the toothed portions of *fblow to ,feed out "the-lowermost strip.

-When it has passed forward from beneath the other strips, the next strip above is perf .mitmdmfallm the'bottom of the magazine into the plane of. the head 37 at some moment when the cut-away face 39 of the head .is presente dfto theside of the magazine as illustrated in F ig. 4:, whereby to leave it momentarily unobstructed. The head aslsumes'thisfposition sofrequently that the feed of .Stripsis never interrupted but one 'isalways being acted'upon. As the head en- .ends 'the lengths thereof .are immaterlal'. The frame33 is preferably resiliently held -..to it sf'Work., For this purpose I may utilize gages the sides of the strips near the leading flbChLggPlVOtt-Bd to an ear of the frame 11 andpassing throughva perforated ear 45 on the frame. A suitable spring 17 is interpos,ed'between the ear 45 and a nut 49 on 1'11, thebolt. V

,;The strips selected from the supplyby the action of the feeder head 37 are, in the illustrated embodiment of the invention, driven forward into cooperation with a pair of fast naled in boxes 57 and 59. The box 57 is connected to the yoke of the standard 9 by means of a pin60 adapted to enter any one of a series of holes 61 disposed in a vertical line. Theopposite box 59 nearer the roll 53 is suspended by a pivoted bolt 63 from a bracket arm 65 andnormally pressed away from the arm by a suitable spring 67 carried by thebolt between the arm and an abutment nut 69? The tension of the spring 67 may be adjusted by means of the nut to vary the pressure of the feed roll on the wood.

By adjustment of the bolt 63 in the bracket arm 65 by means ofsleeve nut 71, the shaft may be swung about pin 60 to vary the position of the roll 53 to accommodate strips of different thicknesses. For the greater variations the bearing box 57' may also be adjusted bodily by changing the pin 60 from one ofthe holes 61 to another.

The "feeder head 37 and roll 53 are designed to be driven at a high rate of speed,

' greater than'that of the main feed rolls 3 of the machine, so as to supply an uninterrupted succession of strips to the machine which operates on them. Toyp'ermit these devices to press forward the series of strips, abutting end to end, to the comparatively slow running "feed rolls 3,'yieldi1'1g'driving means may be provided therefor, the illustrated form of which I shall next describe, referring particularly to Fig. 1.

Theshaft 55 is driven through a pulley 73. "The'shaft 35 carries on its upper end a bevel gear 75 whose center is substantially on the axisof the trunnions 29, whereby its .movement' due to the swinging of frame 33 1S mmnmzed. The gear 75.1s adapted to meshwith the gear 7 7 on a shaft 79 "having "a bearing 81 on the adjustable standard 11 and an extensible'comiection,as bynmeans of a'spline,:with the hub 83 of a pulley 85 ournaled in the standard 9. Provision is thus made for driving the shaft 35 from the pulley 85, no matter in what position of adjustment the standardllgmay be'nioved in order to make the magazine of proper size to receive the strips to be operated on.

i. As. clearly shown in Figs. 2 and 3, the

pulleys 73. and 85 are disposed in substantially the 'sameplane and a pulley87 isyieldingly mounted on the swinging, spring-' pressed bracket 89 carried by standard 9 85, 73 andi'87 to rotate pulleyLSt; in a counliminary feed, as 'when'too great resistance I against the f'force of its supporting spring: I

Figs. 57 and 6 best illustrate means. I have provided for temporarily disconnects ing the feeder head 39 for anyidesired 95; When that portion of the head ofpin 91 which is of-lesser radius is in contact with the screw as indicated in Fig. ,6, t11e. frainewill' hang in. its normal vertical positionuan'd may yield to the left in the operation otthe machine as may be necessary. 'If,.how.ever,' the pin '91 is turned, for. example,:by.means 0153* a suitable hand crank 97; the portion of greater radius 7 win, engage the screw and swing the frameto the left into such;posi-' tion that thetoothed portions llof the disk;

From the description ofthe" illustrative.

lengths may be piledyin the magazine and fed forward without any :break in theprogression. The feeding headBT bears yi'eldingly against the side of the lowermost strip and accommodates itself tojslight variations in the widths thereof, while for major variations the whole mechanism may be readily adjusted.
